Product Details

The blade on this shirasaya katana is forged from T10 high-carbon steel using a clay tempering process that creates a pronounced hamon line running the full length of the edge. The differential heat treatment leaves the cutting edge hard while preserving flexibility in the spine - a detail visible in the undulating temper line against the polished chrome-finish steel. At 40.5 inches overall with a blade width of 1.26 inches and spine thickness of 0.275 inches, the geometry is faithful to classical shirasaya proportions.

The full tang extends through the entire tsuka, providing the structural backbone for a 3 lb assembled piece. Unlike pegged or partial-tang builds, this construction distributes load evenly from tip to pommel, which is especially important at this overall length. For collectors interested in the broader T10 Shirasaya category, this full-tang approach represents the standard worth seeking.

Between blade and handle sits a gold-tone openwork tsuba with a pierced lattice pattern. The warm metallic tone creates a deliberate contrast against the black-and-white marble body, and the collar fittings echo the same gold finish for visual consistency across the fittings.

Both the saya and tsuka are finished in a hardwood lacquer with a marble pattern in black and white - what the image confirms as an ink-splatter style with irregular white patches over a deep black ground. The effect varies across every piece due to the hand-applied lacquer process. A single black sageo cord wraps the saya at the mid-section, providing a clean break in the marble surface and a functional retention point. Collectors exploring the full range of Shirasaya Katana styles will recognize this marble lacquer treatment as one of the more visually distinctive finishes available in this form factor.

Package dimensions are 43.3 x 3.93 x 3.14 inches with a shipping weight of 4.4 lb. The sword stand is not included. This piece is intended for collection and display purposes.

  • Blade forged from T10 high-carbon steel with clay tempering, producing a visible hamon line along the edge and a hardened cutting surface with a tough spine.
  • Full tang construction runs the length of the tsuka, ensuring structural integrity across the entire 40.5-inch overall length and 3 lb assembled weight.
  • Saya and tsuka feature a striking marble-pattern lacquer finish in black and white over a hardwood core, creating a bold, high-contrast visual that sets this shirasaya apart.
  • Gold-tone openwork tsuba adds a refined accent between blade and handle, with a classic pierced pattern that contrasts cleanly against the monochrome marble body.
  • Folded steel construction with a polished chrome-finish blade surface highlights the layered grain and hamon detail - no two pieces are visually identical.
  • Note: sword stand is not included. Blade is hand-finished; handle and saya share a unified marble lacquer pattern for a cohesive shirasaya aesthetic.

Frequently Asked Questions

What steel and heat treatment does this katana use?
The blade is forged from T10 high-carbon steel with clay tempering, producing a distinct hamon line and a differentially hardened edge with a tougher, more flexible spine.
Is the tang full length through the handle?
Yes - the full tang runs the complete length of the tsuka on this 40.5-inch, 3 lb shirasaya, providing solid structural integrity from blade tip to handle end.
How is the marble pattern on the saya and tsuka applied?
Both saya and tsuka are finished in a hand-applied black-and-white ink-splatter lacquer over a hardwood core, so the marble pattern varies slightly on each piece. The gold-tone tsuba and black sageo cord complete the contrast.
